A really interesting article in JEP:
"In fact, the costs of comprehensively genotyping human subjects have
fallen to the point where major funding bodies, even in the social
sciences, are beginning to incorporate genetic and biological markers
into major social surveys. The National Longitudinal Study of Adolescent
Health, the Wisconsin Longitudinal Study, and the Health and Retirement
Survey have launched, or are in the process of launching, datasets with
comprehensively genotyped subjects…These samples contain, or will soon
contain, data on hundreds of thousands of genetic markers for each
individual in the sample as well as, in most cases, basic economic
variables. How, if at all, should economists use and combine molecular
genetic and economic data? What challenges arise when analyzing
genetically informative data?"
